Section 23: Ascending From The Underworld

Ride north to warn Lost Lake Camp. You'll encounter a militia checkpoint shortly after entering the snowy area. Stop near the derelict vehicles, including a red dump truck. A Reacher may patrol the area.

Equip the .50 BFG with a suppressor and sneak towards the checkpoint, staying low on the slope. There are about ten militiamen, with some beyond the truck blocking the road.

Silently snipe the sniper in the watchtower. Avoid the tripwire below by staying on the slope.

Move beyond the outcropping and take out the sentry on the roof and the one on the porch.

Stay on the slope and remove your suppressor. Target the armored foe with the flamethrower below.

Continue sniping remaining hostiles, watching your flanks for enemies approaching from the barricade.

Locate and eliminate the sniper on the rock ledge near the west barricade.

Loot the area for ammo and resources. Return to your bike and ride to the north barricade.

Look for a sentry on the ledge before pushing the truck aside to clear the path. Stop at the police car beyond.

Approach the tunnel checkpoint. Sneak into the brush alongside the road and silently snipe the sniper atop the tunnel.

Move to the snowy knoll and kill the sniper on the short watchtower near the entry.

Eliminate the five additional militiamen, including an armored one with a flamethrower. Try to preserve your suppressor.

Raid the area for remote bombs and ammo caches. Clear the blockade by tossing a gas can near its base and shooting it.

Retrieve your bike and ride through the tunnel. Stop halfway when you see daylight.

Advance stealthily on foot. Snipe the sentry atop the NERO building on the left.

Sneak forward and kill the sniper in the elevated watchtower on the right.

Eliminate the four additional hostiles, including an armored gunner and a flamethrower enemy.

Raid the site. You can use the Gun Locker and purchase ammo.

Push the truck to clear the path in the tunnel, get to your bike, and continue through the tunnel, speeding down the mountain.

Upon arriving at Lost Lake Camp, you'll learn that the militia attacked, Skizzo escaped, and Iron Mike was severely wounded. He dies after asking if you found Sarah and to keep the camp safe.

Exit and inform the survivors of Iron Mike's death and Colonel Garret's intent to exterminate them, as Skizzo betrayed them.

Speak to Boozer and Rikki about a plan to attack the militia's armory and barracks at Wizard Island using a truck and a fertilizer bomb. Rikki agrees to help, focusing on occupying the south side while you draw militia away from the north.
